A logger protocol that provides a common logging interface for different kinds of loggers. In addition, a class with a set of static functions for logging within your code is provided.
Kitura uses this API throughout its implementation when logging.
Add the LoggerAPI
package to the dependencies within your application’s Package.swift
file. Substitute "x.x.x"
with the latest LoggerAPI
release:
.package(url: "https://github.com/IBM-Swift/LoggerAPI.git", from: "x.x.x")
Add LoggerAPI
to your target's dependencies:
.target(name: "example", dependencies: ["LoggerAPI"]),
import LoggerAPI
Add log messages to your application:
Log.warning("This is a warning.")
Log.error("This is an error.")
You need to define a logger
in order to output these messages:
Log.logger = ...
You can write your own logger implementation. In the case of Kitura, it defines
HeliumLogger
as the logger used by LoggerAPI
. You can find out more about HeliumLogger here.
